If you have an account or will open an account at one of these top 10 sportsbooks:
Betonline
Bodoglife
BookMaker
Sign up for an account with BetMyLines, they will credit you back to up to 30% of what you lost.... and you can use that to play at their site... The problem is their mininum cash out amount is $100.00USD. For Example:
If you open an account @ Bookmaker and make a $100USD Deposit, made a few bets or parlays but lose. Thats it.. Right? well, With BetMyLines, you'll have up to $30.00USD of credits to play.... Nice Eh...?
They work as the middleman between you and your favorite sportsbook. They will maximize your money by taking the commission money lost from you and other members and consolidate onto their site so you and other members will still have another opportunity to win back or even more of what was lost.... So the reality truth is...
If you deposit $100 to your favorite sportsbook and you lose it that means there's no other way to win that back, unless if you plan to deposit more....
But with BetMylines, you'll have up to $30 worth of credits to play....
